Please forgive my ignorance if I have missed a comment.
I have been following the development of the KC-46A on here since it's inception, but only from the standpoint of large project management.
Since I have no design or development experience of any aircraft on my CV, let alone a large military aircraft, I have a fairly simple question.
History suggests that although the 767 basic airframe was used, virtually everything else was "reworked" to meet the requirements of the USAF.
Would anyone be prepared to say, what the percentage of new components, (as in designed and manufactured specifically for..) had to be sourced to meet the specific USAF requirements?
Thanks
